I'l give ya the p/n for the belt that I use but I have a 351W with a sag pump, 3G alt and no smog pump. If you don't have the same setup then I guess this won't do you any good. It's a little longer than a 302 belt and a little shorter than a 351 belt(because neither would work).

Dayco- 5060923 costs about $32 at the Zone and about $36 at NAPA.

Im doing some stuff, and this thread reminded me I need to replace my 8 year plus old belt. As info, the stock 94 bronco serp belt with a 5.8 is 102" long. AS IS an E150 with same motor AND F350 with the 3G alt. So apparently there is no need to go longer. I may go to a 102.5" belt since im running a sag and 3g, but wont know till I trial fit the stock length belt.

If you get one (sag bracket) out of an E-series van with R134a, it will use the small bolts like the Bronco. If you get one from an E-series with R12 it will have the thicker bolts that require you to drill out your bolt jounals on the Bronco compressor.

gotta factor in my ford discount as well.

goodyear gatorbacks are supposed to be the shit for the F150s. I always get my discount on parts so I end up with motorcraft. they seem to last anywhere from a 1-1.5years dependig on how many miles I drive it.

I also had to run a longer belt on my bronco with the bronco air pulley and sag pump. you had to force the stock one on so it was hella tight, had to go longer to get a correct fit
